System Sensor COSMOD4W 4-Wire Interface Module

Overview

The COSMOD4W is a 4-wire interface module designed to integrate detection devices into System Sensor i4 Series fire alarm control panels and addressable networks. It operates at 35VDC and provides protocol-level connectivity for distributed fire safety deployments where conventional wired detectors need to communicate across networked architectures. Use this module when you need to bridge legacy or parallel 4-wire detection circuits into an i4 Series addressable system without replacing existing detector wiring runs.

Compatibility

The COSMOD4W integrates with System Sensor i4 Series fire alarm platforms and i3 Series detection devices. It supports addressable network integration for multi-panel or distributed detection scenarios. Verify loop capacity and protocol version with your control panel documentation before installation, as i4 Series panels vary by generation.

Installation Notes

Operating voltage is 35VDC. Confirm your control panel's 4-wire loop power supply meets this requirement and has sufficient current capacity for the number of modules and detectors on the circuit. Mount the module in a secure enclosure away from moisture and extreme temperature swings. Follow System Sensor wiring diagrams for loop termination and polarity — reversed polarity will prevent module initialization.
